The maximum horizontal distance shall be 90 meters (295 feet), from the horizontal cross-connect in the telecommunication room to the work area outlet.

Work area components extend from the telecommunications outlet to the station equipment. Any special requirement in work area cabling (e.g. pair crossover) shall be done outside of the telecommunication outlet.

Each work area telecommunications outlet shall be connected to a horizontal cross-connect in the telecommunication room. A telecommunications room on the same floor should serve each work area.

A minimum of two telecommunications outlets shall be provided to each work area.

Always use suitable connecting hardware and equipment cables to make the connection to telecommunications equipment.

2.3 Backbone cabling

The purpose of vertical cabling (backbone cable) is to provide interconnection between telecommunication rooms, equipment rooms and entrance facilities. The vertical cabling consists of vertical cables and backbone cross-connects.

The use of UTP cable should be limited to a maximum distance of 90 meters (295 feet). See Appendix D for CTAG approved cable and connecting hardware recommendations.

2.5 Pathways and spaces

2.5.1 Horizontal pathways

Horizontal pathways are the routes taken for the installation of cable from the telecommunications room to the work area. The pathways can be composed of cable tray, conduit, under floor duct, and ceiling spaces

2.5.2 Backbone pathways

Backbone pathways consist of conduit runs or risers going between floors, and are used to connect telecommunications rooms.

2.5.3 J-Hooks

J-hooks are to be used to support telecommunications cabling within ceiling spaces. They should be spaced (to a maximum) of approximately 4 feet apart. Cable pathways should follow a prescribed route going over top of heating ducts and other conduit if possible.
